<p>Rating: 5 stars</p><p>You can always count on CPAN to have prewritten modules for various things, including this one. I've never bothered before about portability and just rely on the &quot;which&quot; command, but for one reason there's a time when I just couldn't do that.
<br><br>Btw, there's also File::Which::Cached.</p>Steven Haryanto2010-08-25T11:19:36
